Title: Detector
Inventor: JIEIMUSU II RABURATSUKU
IPC: G01N30/64
Filed: 1987-03-27
Abstract: PURPOSE:To enable highly accurate detection of a sample gas ionized, by providing a means to turn ON or OFF discharge of ultraviolet rays in a short time than the transition time of a detection gas by ultraviolet rays in a windowless light ionization detector. CONSTITUTION:A gas for generating ultraviolet rays is supplied into a container 11 at an inlet 16 and a potential sufficient to generate ultraviolet rays is supplied between a cathode 18 and an anode 26. At the same time, a sample gas containing a gas to be inspected is introduced together with a carrier gas through an inlet 24. The sample gas is ionized by the ultraviolet rays to be collected with a collector electrode 28. The pulse frequency of a power source which applys a voltage to the cathode 18 and the anode 26 is made shorter than the transition time of ions. This suppresses background as caused by the ionization of released gas from the inside of a container 11 and others.

Abstract: PURPOSE: To increase the quality of reproducing signal and the focus error detection sensitivity, by coinciding the center of light flux of the emitted light of semiconductor laser into the center of focussing lens and providing the lens for focus error detection outside the focussing lens.  
     CONSTITUTION: The center of light flux of the emitted light 14 of the semiconductor laser 1 is incident to the focussing lens 14 with mated light axis. Further, the center of light flux of the emitted light 15 is incident to the lens 17 consisting of the center of round type convex lens with shifted light axis non-orthogonally, if the interval between the information record carrier 6 and the collection lens 4 is changed, the reflection light 20 moves to the direction in crossing with the light axis. Accordingly, when the two-split photodetector 10 is adjusted so that the output of the differential amplifier 11 is zeroed when the surface of the bit 7 of the information recording carrier 6 is placed at minimized position of the light spot 5, the minimum spot 5 can be collected to the recording carrier 6 automatically with the lens shifter 12. Thus, the quality of reproducing signal and the sensitivity of focus error detecting sensitivity can be increased.
